Abstract(in English) | A reconfigurable systolic array processor based on a coordinate rotation digital computer (CORDIC) algorithm is proposed for MIMO-OFDM baseband processing. With CORDIC, the processor provides high computation efficiency, and a multi-thread interleaving architecture offers the advantage of a simple data transfer mechanism. Also presented are an array mapping method for calculating MMSE filter coefficients and a comparison of the performance with other conventional processors, including EVP and ADRES. The processor achieves a computational density of 213% that of EVP. And, the processor achieves a active processing element rate of 213% that of ADRES. |
